HOISTING- MECHANISM.

To all whom it may concern:

Be .it known that I, MENNO S. YooER, a citizen of the United States,residing at Shipshewana, in the county of Lagrange and State of Indiana,have invented certain new and useful Improvements in Hoisting Mechanism,of which the following .is a specification.

The present invention relates more particularly to hoisting mechanism ofthe character disclosed in a former patent granted to me on June 8,1909, No. 923,923.

The primary object of the present invention is to provide apparatus thatis Very simple in its character, so that it may be built and installedat less cost, and furthermore is so arranged that it may employ any wellknown type of cross draft carrier for the hoisting mechanism.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a vertical sectional viewthrough a circular or polygonal barn, showing the hoisting mechanisminstalled therein. Fig. 2 is a planfview of said apparatus. Fig. 3 is adetail plan of one of the angles of the supporting frame. Fig. 4 is across sectional View through the track, showing the method of supportingthe frame. Fig. 5 is a detail View showing one type of hoistingmechanism that may be employed.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

The barn is designated generally by the reference numeral 6, and locatedin the up per or roof portion thereof, is a circular continuous track 7that may be of any suitable type. Arranged beneath this track, is asupporting frame, which is preferably in the form of an open ringcomprising angularly disposed sections or beams 8, the ends of whichcome together, and are secured by brace plates 9. Brackets 10, securedto the frame at the angles thereof, straddle the track 7, and haverollers 11 journaled thereon and operating on the track, as will beclear by reference to Fig. 4. Forming a part of this frame is across-draft carrier 12, which may be of any well known type, saidcarrier having rollers 13 that operate on the track, and being alsoprovided with a pulley 14 over which the hoisting cable 15 passes, aclutch being also preferably provided for holding the load at any heightdesired.

Specification of Letters Patent.

hoisting cable, has mounted thereon, suitable sling pulle s, hooks 16,or other devices for engaging t e article or material to be hoisted, aswill be obvious to those skilled in the art. At each of the angles ofthe supporting frame is arranged a set of fingers comprising anoutstanding finger 17 and an upstanding finger 18, the latter beingdisposed just outside the bracket 10. For the purpose of rotating theframe, oppositely extending cable sections 19 are employed that restupon the outstanding fingers 17 and bear against the fingers 18. Thesecables 19 have their upper and rear ends crossed, as shown in Fig. 2 andsecured at separated points to the supporting frame, as shown at 20. Thecables pass over suitable pulleys 21 suspended in the barn. One of thesecables then preferably passes downwardly around a guide sheave 22, andis arranged to be detachably connected to the whifiietree 23 or to anyother suitable means for drawing the same. A like device may beconnected to the other cable section, but in the preferred form ofconstruction, automatic means for returning the frame is employed. Inthe form illustrated in Fig. 1, this automatic means consists of aweight 24 having a pulley 25 that runs upon the cable section, and saidsection has its free end secured in the upper portion of the barn, asillustrated at 26.

Briefly described, the operation of the mechanism, shown, is as follows.Material to be elevated, is engaged with the hoisting mechanism and israised to the desired height. Then by drawing upon the rotating cablesection, the frame with the load supported thereon can be turned tocarry the said load to any point desired. After the article or materialhas been disengaged upon relieving the cable section of the strain, theweight 24 which has been elevated by the above described operation, willreact, and consequently turn the frame in an opposite direction. On theother hand, if it is desired to remove an article or some material fromthe barn, a reversal of the above described operation is all that isnecessary. It will be obvious that this structureis exceedingly simpleand that it has many advantages, not only because of its cheapconstruction, but inasmuch as it permits the use of a cross draftcarrier on a circular track. When it is desired to unload in the otherside of the barn, the weight is put on the other cable. If it is desiredto unload on both sides alternately or at any time, no weight is usedand the cable is in one continuous piece passing through a sheavefastened to a stake in the ground at a proper distance from the barn.Also a two drum power hoist can be employed, using one drum for thedraft cable and the other for the two sections of rotating cables whichare wrapped around it in opposite directions. Means are provided to thehoist for positively reversing the motion of the latter drum of thehoist.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without depart ing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination with a circular track, of a supporting framerotatable thereon,
